IEC 61753-1:2018
Fibre optic interconnecting devices and passive components - Performance standard - Part 1: General and guidance
Product Details
a) definitions updated with new products: wall outlets, wall or pole mounted boxes, splices, ODF modules, street cabinets, hardened connectors and field mountable connectors;
b) categories U and O are replaced by categories OP and OP+. No mandatory sequence in category OP+. Category OP+ contains the tests from category OP with the addition of only 4 other tests;
c) addition of Category I (Industrial);
d) temperature ranges added (with the HD suffix to the categories C, OP, OP+ and I) in case passive optical components are placed in a housing together with active electronics (HD stands for “heat dissipation”);
e) the height of category A changed from 3 m to ground level (0 m);
f) the lower level height of category G environment changed from ground level (0 m) to –1 m below ground level. Upper level remains at 3 m above ground level;
g) addition of performance tests, test severities and performance criteria for new products: Wall outlet, wall or pole mounted boxes, mechanical splices, fusion splice protectors, ODF modules, street cabinets, field mountable connectors and hardened optical connectors;
h) test severity of Mating durability test for connectors in categories C, OP ,OP+ and I is reduced to 200 cycles for connectors with cylindrical ferrules and 50 cycles for connectors with rectangular ferrules;
i) test severity of Change of temperature test for connectors and passive optical components in category I is reduced from 20 cycles to 12 cycles (harmonized with connectors and components from other categories);
j) test severity of Flexing of strain relief test for connectors in categories C, OP and OP+ is reduced to 50 cycles;
k) test severities of Assembly and disassembly of fibre optic mechanical splices, fibre management systems and closures test for all enclosures is reduced to 5 cycles;
l) test severities of Change of temperature test for all protective housings in categories C, A, G and S is reduced from 20 cycles to 12 cycles (harmonized with connectors and components);
m) test severities of Resistance to solvents and contaminating fluids test for closures in categories G and S changed – kerosene is removed, diesel oil exposure reduced to 1 h immersion and 24 h drying at room temperature;
n) sealing performance criteria of sealed closures for categories G and A are reduced to 20 kPa overpressure.
o) the change in attenuation criterion for connectors has changed from peak-to-peak into a +/- deviation from the original value of the transmitted power at the start of the test (harmonized with the change in attenuation criterion for components, splices and protective housings).
